histf
Histogram of a vector/scalar field

Description ```H = histf(F) computes the histogram H of the field(s) F into 100 equally spaced bin. The appropriate range of bins is estimated from the rms of the first field. H = histf(F,BIN) computes the histograms among the bins specified by the vector BIN. BIN can be in the form LINSPACE(-X,X,N). If F is a 2-components vector field, use [HX, HY] = histf(F,..) to compute the histogram for each component of the vector field. Similarly, if F is a 3-components vector field, use [HX, HY, HZ] = histf(F,..) [...,BIN] = histf(...) also returns the bins vector BIN used for the computation of the histogram. This is useful if BIN is estimated by histf itself. By default, histf considers the values 0 as erroneous, and does not include them in the histogram. If however the values 0 are to be included, specify histf(...,'0'); Example v = loadvec('*.vc7'); [h,w] = histf(vec2scal(v,'rot')); semilogy(w,h,'ro-'); See Also histscal_disp, statf, corrf, ssf, vsf.
